26 Getting Familiar With Your BASIC Interface Software

Status Bar

The BASIC software status bar is at the very bottom of the user

window and is divided into five sections.

COM Port Status

COM Port Status has two functions. If you select a standard RS-232

COM port, the window contains the following information:

• Availability of the selected COM port

• Selected COM port

• Communication rate

• Parity

• Number of bits per character

• Number of stop bits

• Type of data flow control used (Xon/Xoff or None)

For example, COM1: 1200 N 8 1 None would indicate that the selected

COM port is COM1 and COM1 is configured for 1200 Kbps, no parity,

8 data bits per character, 1 stop bit, and no flow control. Or, X COM2:

19,200 E 7 2 Xon/Xoff would indicate COM2 was selected at 19,200

bps, with even parity, 7 data bits per character, 2 stop bits and

Xon/Xoff data flow control. However, the X in front of the string

indicates that COM2 is not available.
